There's a little ditty that MS released a while back that lets you open LZH/LHA folders the same way you can CABinet files. It also has one of those extraction wizards like with ZIP files. Trouble was, it was only in Japanese. So for fun, here's an english translation of the thing - or, an installer for the translated dll. Ironically, it's in a zip folder ;*)
